Skyscraper Index
The Skyscraper Index is a concept put forward by Andrew Lawrence, a property analyst at Dresdner Kleinwort Wasserstein, in January 1999, which showed that the world's tallest buildings have risen on the eve of economic downturns. Business cycles and skyscraper construction correlate in such a way that investment in skyscrapers peaks when cyclical growth is exhausted and the economy is ready for recession.
